Fluoroantimonic acid is a mixture of hydrogen fluoride and antimony pentafluoride, containing various cations and anions (the simplest being H 2 F + and Sb F − 6).This mixture is a superacid that, in terms of corrosiveness, is trillions of times stronger than pure sulfuric acid when measured by its Hammett acidity function.
Antimony pentafluoride is the inorganic compound with the formula Sb F 5.This colourless, viscous liquid is a strong Lewis acid and a component of the superacid fluoroantimonic acid, formed upon mixing liquid HF with liquid SbF 5 in 1:1 ratio.
Magic acid (FSO 3 H·SbF 5) is a superacid consisting of a mixture, most commonly in a 1:1 molar ratio, of fluorosulfuric acid (HSO 3 F) and antimony pentafluoride (SbF 5).This conjugate Brønsted–Lewis superacid system was developed in the 1960s by Ronald Gillespie and his team at McMaster University, [1] and has been used by George Olah to stabilise carbocations and hypercoordinated ...
As fluoroantimonic acid is often mixed in a 1:1 ratio, [Sb 2 F 11] − is the dominant anion in the solution. Further, solvated protons are not limited to [H 2 F] + , and can form heavier cations such as [H 3 F 2 ] + or [H 4 F 3 ] + , leaving more SbF 5 to react and form higher fluoroantimonate ions.
The combination of kojic acid, 10% glycolic acid and tranexamic acid “act synergistically for brightening skin overall and lightening dark spots,” says Castilla, who notes that it’s a ...
Sagging Skin “Ozempic face” may sound scary, but sagging cheeks, deep wrinkles, and a lax jawline can happen with any rapid weight loss, says Patricia Mars, MD, a plastic surgeon in Tucson.
For example, fluoroantimonic acid, nominally (H 2 FSbF 6), can produce solutions with a H 0 lower than –28, giving it a protonating ability over a billion times greater than 100% sulfuric acid. [5] [6] Fluoroantimonic acid is made by dissolving antimony pentafluoride (SbF 5) in anhydrous hydrogen fluoride (HF).
